Check Box Filetr

Hi,
i am trying to add a check box filter using master_checkbox, but it seems that the “master_checkbox” is not linked at all to filtering , it is just used to check/uncheck all column values .
pls could anyone help me to link master_checkbox to filtering (to get all values that checked or not)??

Unfortunately your requirement is not clear. How should master_checkbox be linked to filtering?

to get all values that checked or no
You can get ids of checked rows with getCheckedRows(col_ind) method docs.dhtmlx.com/doku.php?id=dhtm … heckedrows

i want to link master_checkbox to filtering as following:
if i checked it : i get all rows that have this column checked
& if i unchecked it : i get all rows that have this column unchecked.
like the text filtering if i write “A” : i get all rows that have in this column letter “A”.
How& where can i modify master_checkbox code to work that way ??

i want to link master_checkbox to filtering as following:
It can be done only with code modification or with custom shortcast creation docs.dhtmlx.com/doku.php?id=dhtm … s_creation

master_checkbox declaration is placed in the dhtmlxgrid_filter.js file
